This evening, during further tests looking for G6ALB's earth-mode beacon signal on 8.76kHz, I discovered that best results receiving at my QTH 3km from Andrew were with a small E-field probe rather than a loop or earth electrode pair. With the EFP, signals could be detected in my upstairs shack with just a 19inch whip! This suggests that the electrostatic component is the dominant one rather than magnetic or simple potential difference measurable between the 2 earth electrodes. My basic physics is very rusty and any help clarifying what is going on would be appreciated. It now means we may have a much easier way of detecting utilities assisted earth-mode signals at greater ranges as the positioning of the EFP was far less critical than trying to detect signals with a loop lying on the ground.
Comments please?
